Windows 10 comes in several different editions: Home, Pro, Pro for Workstations, S, Education, Pro Education, Enterprise, Enterprise LTSC, X, IoT and Team. The remaining options (with Bing, Starter and Ultimate) have been used in past Windows editions but are not available with Windows 10.
Windows 10 has several editions, all with varying feature sets, use cases, or intended devices. Certain editions are distributed only on devices directly from an original equipment manufacturer (OEM), while editions such as Enterprise and Education are only available through volume licensing channels. Microsoft also makes editions of Windows 10 available to device manufacturers for use on specific classes of devices, including IoT devices and previously marketed Windows 10 Mobile for smartphones.
